I have a shop build in Magento 2.2, I am using Ebizmarts_SagePaySuite for payments.
I just have a call with Sagepay to ask if I need to do anything for the 3D secure change. They say that Magento should use Transation Protocol 4.
Do you know where I can confirm is Magento 2.2 uses Transation protocol 4?
Thank you very much in advance
